Working principle：
The SCJ-BX01 portable Doppler ultrasonic flowmeter is a device that uses the Doppler effect of ultrasound to measure water flow velocity and flow rate. It integrates a signal processor and a proprietary flow rate calculation algorithm, which can quickly and accurately calculate water flow velocity without calibration or drift. The device is equipped with a TFT LCD screen and a lithium battery, allowing for quick measurement of water depth, flow velocity, flow rate, and other data on site without manual calculation. The device has data storage and export functions designed for fast and portable measurement of water flow velocity and flow rate;
Main features:
The sensor integrates a pressure water level gauge internally, eliminating the need for an external water level gauge to achieve integrated monitoring of water level, flow rate, flow rate, and water temperature;
Wireless connection is used between the handheld device and the sensor, without cable constraints, making it more convenient for multiple people to operate;
Equipped with a built-in lithium battery and a standard Type-C USB interface, it can be connected to a computer or charged;
Comes with a built-in keyboard and LCD, easy to operate, intuitive reading, direct output of results, no need for secondary calculations;
The measurement accuracy of flow velocity is high, and there is no drift, no need for calibration;
The Doppler ultrasonic flowmeter probe has an IP68 waterproof rating, ensuring the reliability of underwater operation;
Compact size, easy installation, and less obstruction to water bodies;
Comes with a matching suitcase and measuring rod, easy to use;
The wireless acquisition module and cable can be directly fixed to the measuring rod, avoiding cable clutter and facilitating operation;
The handheld device is connected to the sensor probe through wireless communication and can be hung on the body, freeing both hands and avoiding damage caused by the handheld device falling into the water;
